Installing fbsimctl in Travis - ios

Question

I'm working on a new build travis which integrates e2e tests on iOS but I'm having problems installing fbsimctl. I want to use detox, and this is one of the prerequisites to use it.
This is the log when trying to install it:

The command "brew install fbsimctl --HEAD" failed and exited with 1 during .
The cache permissions I've granted are these:

But I don't know what else do I need.
Thanks

Fbsimctl is no longer a dependency of Detox since we had lots of trouble with it, mainly because it is not always stable and there's no way of getting a stable version.
If you have issues with Fbsimctl, open an issue in fbsimctl's GitHub page.
Unrelated to Detox, if you still want to install Fbsimctl, you can install the latest stable version 0.4.0 (Apr 2017) by brew install fbsimctl#0.4.0
